Abstract

Waste management has received global attention both in academic discourse and in practice. However, with much emphasis on urban centers, but much more regrettably, with inadequate attention to waste management of urban slum residents. This observed gap has created paucity of data for waste policy makers and researchers, a situation responsible for the failure municipal authorities to effectively and efficiently manage the waste problems of slum dwellers. Hence, this study strives to assess waste collection and disposal systems of slums residents in Ibadan city. Purposive, multi-stage and random sampling techniques were used for the study. Purposive sampling was used in selecting Ibadan North among the six urban local government areas in the metropolis. Multi-stage sampling was used in identifying four wards with relatively homogenous slums in the core areas of the Local government. Three slum localities were randomly selected across the four identified wards. The 1991 census figure for the sampled localities was projected to 2010 at 3.2% growth rate adopted for urban centers, which amounted to 132,639. Using an average household size of six for high residential areas, the estimated housing stock in these areas was 22,106. About 1.3% of the estimated housing stock in these areas was used as the sample size, this give a sample size of 300. Thus, 300 household heads were randomly surveyed across the selected slum areas. Both descriptive and inferential statistics (ANOVA and Pearson Product moment correlation) were employed for the analysis. The study revealed that urban slums dwellers in Ibadan city were mainly low-income earners, as two-thirds (69.3%) respondents earn below N10, 000 ($27.78). A one way ANOVA was used in testing for variation in waste disposal methods adopted by slum dwellers across the selected areas. The results revealed that burning was slightly significantly varied across selected slums (F [1,298] = 2.99, p= 0.09); while dumping in rivers with (F [1,298] =0.01, p= 0.92) and use of designated bins (F [1,298] = 0.14, p= 0.70) respectively do not significantly vary across the selected slum areas. The study posited that urban environmental problems and inadequate infrastructural development, especially of waste disposal facilities and collection systems are the bane of waste management in urban slums. The study therefore concludes that upgrading and formalization of slums and squatter settlement coupled with provision of infrastructural facilities and public enlightenment and development control are measures needed to effectively tackle waste collection and disposal systems in developing countries.
